r 5 claims. This invention relates to conventional paper bags, such as used by storekeepers, particularly the grocer for placing articles of merchandise for vconvenient handling by the purchaser. More particularly, the invention relates to means for forming a reinforced handle structure for bags of this kind, as lwell as in the method of constructing and applying handle members to opposed sides of the bag. The novel features of the invention will be best understood from the following description when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed, and in which the separate parts are designated by suitable reference characters in each of the views, and in which:

Fig. 1 is a perspective diagrammatic view of a paper bag, showing one form of handle construction which I employ. v

Fig. 2 is an enlarged section on the line 2-2 of Fig. 1, illustrating the handle in operative position.

Fig. 3 is a view similar to Fig.2, showing a modified adaptation of the invention.

Fig. 4 is a perspective exploded view illustrating the manner of assembling the handle members with upper edge portions of a paper bag.

Fig. 5 is a view similar to Fig. 4, showing another adaptation of the invention.

Fig. 6 is a plan view of a blank on which handle members shown in Figs. 1, Zand 4 areformed; and

Fig. 7 is a view similar to Fig. -6 of the blank, employed in forming handle members as illustrated in Figs. 3 and 5.

In the construction of paper bags, such as used by grocers, bakers, dealers in vegetables, vand other establishments, these bags have been left plain, and used as a wraper for a single article, or as a means for holding a number of articles together in a single package, and unless tied with a string or cord, such bags when filled have necessitated carrying in the arms.

It is the purpose of my invention to apply to paper bags of the kind under consideration, in a simple and practical manner, reinforcing mem.- bers which form in conjunction with cutout side walls of thepaper bag handle members by means of which a bag of the kind under consideration may be conveniently carried in the hand.4 In addition to providing a handle for bags of the kind under4 consideration, these members also ,serve ,to support the upper open end of the bag4 in a closed or partially closed position retaining (o1. 229-54) I i articles against displacement from the open end of the bag.

While` the invention is herein described as applied specifically to the conventional paper 5 bag, it will be apparent that the same is also applicable for use in connection with what is known as shopping bags, composed of heavier and stronger materials, and which would dispense with the use of conventional cord handle now l used on such shopping bags.

In Figs. 1, 2, 4 and 6,-is shown one adaptation of the invention, in which the paper bag is generally indicated at III, and in practise, upper opposed i a side walls II, I2 of the bag have semi-circular l die cuts I3 to form flaps I4, I5 respectively.

.At I6 in Figs. 4 and 6 isshown a blank from which independent handle members I'I and I8 are to. be formed. The blank comprises a rectangular sheet of thick paper or light cardboard die cut centrally and transversely, as seen at ,25\ a fiap 22 foldable along the line 23.

The handle member I1 has a crescent shape opening 24, cut from the material thereof, and substantially similar in form to the opening 3o formed in the handlemember I8, when the flap 22 is in folded position. These registering openings are adapted to receive the fingers of a hand when carrying a bag. The handle members include outwardly and downwardly turned iianges 25 at their upper edges which are disposed upon and secured to the outer surfaces of the opposed walls l I and I2 of the bag.` The remainder of the body portion of the members I1 and I8 being disposed upon the inner surfaces of these walls,

as will clearly appear from a consideration of Fig. 2l of the drawing.

In securing the handle members in position, the die cut and scored blank I6, as vseen in Fig. 6 of the drawing is'coated onv one surface with a V suitable adhesive, and then folded centrally to have the flaps 25 stand outwardly and laterally in the manner seen in Fig. 4, and when so posit tioned. the blank is placed between opposed walls Il, I2 'of a bag, bringing the cutouts 2l, 24 in registering alinement with the die cuts I3, after II and I2.

fter the parts have been securely adhered together, the walls II and I2 are spread apart by rupturing the blank I6 at the points 20, thus leaving one handle member I1, I8 on each of the opposed walls II, I2. In constructing the blank I6, the blank is also scored centrally and longitudinally to form a fold line 26, so that in the event of excessive lling of the bag with merchandise, said walls II and I2 will fold centrally and longitudinally of the handle members, thus eliminating any strain upon the sidewalls of the bag adjacent the ends of said handle members.

Bearing in mind that the entire bag construction is for a give away bag, added expense in the cost of producing the bag is minimized. It will be understood where expense is not a factor, the upper edge portion of the side walls II and I2 of the bag may be reinforced in a number of different ways to give added strength to the entire bag structure.

In the use of the bag, it will be apparent that the tongue or ap 22, with the paper ap I secured thereto will be free to pass through the opening 24 and the handle member I 1, and folded into the position indicated in Fig. 2. in carrying the bag in the hand. In such uses, the nap I 4 may be folded inwardly in the manner shown in said gllre.

In the construction shown in Fig. 2, the surfaces of the handle members I1 and I8 are brought into close proximity into each other, resulting in a corresponding relationship of the side walls II and I2 of the bag. However, in Fig. 3 is shown a slight modication, wherein a relatively thick handle is provided by flaps which retain the walls in spaced relationship to eachl other. While this member is applicable to handle members constructed from blanks of the general contour shown in Fig. 6, I have shown this feature of the invention as applied to modified form of blanks, illustrated at 21 in Fig. 7 of the drawing, and it is shown in a folded position in Fig. 5.

The blank of Fig. 7 diiers in three primary respects, first in that the flange portions 28 are arranged adjacent each other on the blank and separated by the die cut 29, having the weakened ends 30 similar to the weakened ends 20, and that the die cuts 3I in the handle member 32 are of different shape, to form more or less oblong iiaps 33v on both handle members, and further, that both of the iaps 33 have score lines 34,

n which form narrow flange edges 35.

With this arrangement of the parts on the blank, the blank is folded into the M formation shown in Fig. 5 in assemblage of the blank with side-walls 36 and 31 of a paper bag so that the two iianges 28 flt between the walls, and will be disposed on innersurfaces of the walls, whereas the handle members 32 will be disposed on outer surfaces of the walls. In other words, a reverse of the arrangement shown in Fig. 4.

With this construction, the side walls 36 and 31 of the bag will have cutout apertures 38, which will register with the flaps 33, including the flange i ing. This forms, of the overlapping aps 33, a4

thickened handle portion which will eliminate the cutting action on the fingers of the hand in carrying a heavily loaded bag, as might be the case with a structure as seen-in Fig. 2 of the drawing. The blank 21 is also scored centrally and longitudinally to form a fold line 39, similar to the fold line 26, whichr would become effective only as and when the bag walls 36, 31 are spread apart beyond the limits of the flanges 35.

It will be understood that the blanks shown in Figs. 6 and 7, which are foldable in the manner illustrated in Figs. 4 and 5 still adapt them for automatic formation and assemblage in paper bags, thus minimizing the cost of producing handled bags of the kind under consideration, andV further will dispense with as much hand labor as possible in the production of the bags.

In the modication illustrated in Figs. 3, 5 and 7 of the drawing, the tongues have been omitted from the opposed walls of the bag in forming the openings 38 simply to illustrate another adaptation of the invention. It will be apparent, however, that the tongues similar to the tongues I4 and I5 may be attached t'o the naps 33. Inlike manner, it will be apparent that the flaps or tongues I4, I5 of the structure shown in Figs. 1, 2 and 3 may be omitted.

Having fully described my invention, what I claim as newand desire to secure by Letters Patent is:

1. The method of forming reinforced handles for the upper open end portions of paper bags, which comprises forming finger receiving apertures on opposed walls of the bag adjacent the open end thereof, die forming and scoring a duplex handle blank to form finger receiving apertures on wide portions of the blank, folding the blanks centrally to dispose the finger apertures of the wide portions thereof in position for registration with each other, then mounting the folded unit upon opposed walls of the bag with the apertures of said wide portions in registering alinement with the apertures of the bag, securing the unit tosaid opposed walls, and then severing the unit centrally to form on ach of the opposed walls of the bag an independent handle portion.

2. .The method of forming reinforced handles for the upper open end portions of paper bags, whichY comprises forming finger receiving apertures on opposed Walls of th'e.` bag adjacent the open end thereof, die forming and scoring a duplex handle blank to form linger receiving apertures on wide portions of the blank, folding the blanks centrally to dispose the finger apertures of the wide portions thereof in position for registration with each other, then mounting the folded unit upon opposed walls of the bag with the apertures of said wide portions in registering aline-v ment with the apertures of the bag, securing the unit to said opposed walls, then severing the unit centrally to form on each of the opposed walls of the bag an independent handle portion, and including on said duplex blank foldable ange portions arranged upon and secured to surfaces of said walls of the bag opposed to that upon which the wide apertured portions are secured.

3. A device for forming dual handles for paper bags, said device comprising a blank having a long central cut to divide the blank into similar side portions joined by two short uncut weakened rupturable parts at side edges of said blank and ends of said cut, each side portion comprising a wide part and a narrow part foldable one with respect to the other, and each wide part having a cutout to form a linger receiving aperture and to form of each' wide part a handle member.
